print name using for loop php

Question

Using for loop in PHP can we have numbers associate with a variable name?

ex:

$name1="hi";
$name2="khj";

for($i=0;$i<=2;$i++)
{
echo ..
}

How can we print $name1 and $name2 using for loop?

Thanks!

Yes this is called variable interpolation.

$name1="hi";
$name2="khj";

for($i=1;$i<=2;$i++) {
    $var = 'name' . $i;
    echo $$var;
}

Note: There are multiple syntaxes for variable interpolation in PHP. Also, I modified your loop to start at 1.

    for($i = 1; $i <= 2; $i++)
    {   
        echo $name{$i};
    }

It would be way easier to put it in an array though, that's what we have them for.

    $names = array();
    $names[1] = 'A';
    $names[2] = 'B';

    foreach($names as $name)
    {
        echo $name; 
    }

Better to use something like:-

$names[] = $name1;
$names[] = $name2;

foreach($names as $name){
    echo $name;
}

This is not what the user is asking.

Don't think so. Test it yourself. Your output, as you noted, is name1 and name2.

If your answer "matches" with everybody else, why bother writing a new answer. Just upvote the one you think is the best answer.
